I bought a BFG gtx 260 maxcore off someone from the site here a few months back and the person I bought the video card from names slips my mind. Can I RMA the Card because it fails to work any longer, the fan spins but the motherboard doesn't recognise that it is plugged in, what I thnk might have happened is that my last motherboard went and it is possible that it took out my vid card also :( .
so is it possible to RMA this card and how would I go about it or what are my options?

I don't believe BFG has a transferable warranty. So you would need the original owner's invoice and have them send it in if it was registered to them. If it was not registered, you might be able to get away with it. I'd phone them and say you bought the card but don't have the invoice anymore, and see what they have to say. Check their website for warranty and policy info, too.

To be honest, I assume that anything I buy secondhand does not have a warranty, and factor that into my purchasing decision.

Edit: and if you bought the card on here, and did an iTrader rating, you should be able to narrow it down to who you got it from.
